I have a DVD system in mine. It is actually a 4Runner DVD system with an adapter for the Sequoia's ceiling trim. It has a 7in. screen, comes with 2 IR headphones and an integrated FM modulator for the Radio to hear it over the normal speakers and 2 jacks for normal wired headphones. In addition you can run I think up to 4 wireless headphones. It was installed by the dealer. You can put the kit in either sunroof or non sunroof versions. Price wise was like 1500.00 installed and falls under the trucks warranty.
